T 0 all whom it. may concern -Be it known that 1, PETER J. Sumo, a citimm. the United States, residing at Birmingham, in thecounty of Jefierson and State of. Alabama, have invented new and useful Improvements in Dies for Macaroni and Thick Fluid/Substances, of which the following isaspeoification.

My invention. relates .to arr-.improvement in-detachable circular macaroni molds and likemolds for use in presses for .thick.fluid suhstanwaand my object is to protect the mold, which isthick, heavy and formed of softcopper, from becoming injuredbybe- 7 ing. constantlydropped upon the. cross braces or spider support therefor at the bottom of the presscylindenp i Q 1. According -.to .-the present practice 111 malt-- ing macaroni, presses having relatively small cylindershare given the best results and the most. uniform product: These. presses have at theirflbottoius strong metallic crossbars onspidersuppmtsupon which the macaroni moldh is ,vdetachably supported... These .bars maybela f anged as-a spider having alsolid center. and four radiallarms which are atri tached at their ends to the bottompt the cylinder, or thedmrs maybe. arranged as cross barsand. disposedin parallelism, there being two or more accordingto the sizeoi the. pressicylinder. -.-ln each case the macaroni moldhassp aces leftfreeifrom perforations-which correspond tothe arrangement ofic ross bars, These moldsare lowered by hand: intocthe press cylinder andthezopr erator endeavor-ate adjust ,the. mold. so that as itialls its un perforated spaceswill strike the .crossbarsor web thereby. avoiding in.-

juryto the mold which would; result. if the perforated portionsof the soft-heavy mold struck thecross bars- As azmattervof fact, it rarely, happens .thatthe heavy. mold will an as desired and consequently after use for a comparativelg.short time, the rep or rows of macaroni oles bordering the unperforated spaces become mashed in, and frequently entirely closed thereby-l materially decreasing the availablep-routpnt. from the mold and necessitating the mold being sent. at; eonsiderablaexpense, to;be..-repaired; All

this is avoided by the provision ofraised;

bearing surfaces along the under side of .the unperforated portions of the mold and I prefer to form these surfaces of a hard metal plate attachment instead of making them integral with the mold.

.-To' this .end I provide a reinforcing or hearing: plate ,atta'chment for .thebottom face of the mold, forming it preferably by stamping. it. outof thin sheet metal. 1n a form which will coverythe unperforated poi.- tions of themoldwhenattached. thereto and provide .a bearing surface suflicientl-y raised tofprotectthe .per forated portions of..;the

mold ,from striking ,ony .part of the cross barsprspiden orfrom hem g injured when th'inold is outlofthe cylinder.-.

l Thishein lgenerally the object of my inven't1o'n,-. I are illustrated the preferred embodiment thereof in .the. accompanying drawings .forrning a part of the specification and in whiclrz F'gurel is aside elevation of a macaroni press, ,the cylinder being. broken .away. to show my improvedmold in position therein. EigLIQ-isa bottom lan view of a macaroni mold. With raised caring surfaces formed by anattached plate. Fig.3 is a plan :view of the bearing. plate detached. Figs. a. and

imilar reference numeralsrefer to similar parts throughout the drawings. .Ihave illustrated myinvention in connec-v tionwith a standard form of macaroni ress having a cylinder 1 into which the p astic material is introduced in. bulkier the purpose of being expressed into any of the va llOllS forms of macaroni according to the characteixof iopenings in the. mold 2.. This mold is supported upona heavy metal cross brace or spider ,3 hayingtransverse websd and end portions 5 and. 6, which-are respectively connected to .and supported by uprights .7 and 8. The cross-piece has a pe ripheral ortion 9, which projects into and forms a s oul'der at thehottom of the cylinder 1,.. Themold is formed of a thick heavy copper plate providedwith suitably shaped openingslO which;may; ormaynot have. acentral .pin. (not shown),'ac.cordin to the character of. the macaroni to heme, e.

The mold is shown in bottom plan View in Fig 2,- where rseen .to-he a; circular plate having quadrant shaped groups bf holes 10 which are separated by unperforated diametrical cross spaces 11 and the peripheral rim space 12 which conform to the size and arrangement of the webs 4: and the shoulder 9, respectively, which form the g raised bearing surfaces in- 2 maepes supports for the mold. This arrangement is necessary to permit the plate when dropped into position in the cylinder, to be adjusted by hand until the spaces 11 come 0 posite to and stand over the webs of the spi er. This prevents the spider blocking or chocking any of the macaroni openings. It is very rarely the case that the late, as it is dropped, will fall on the spider so that its unperforated portions only will strike the spider. It follows therefore that the s ider will strike and indent the plate, and find in practice that these indentations usually occur anywhere within a space corresponding to that between the lines aa and ab of Fig. 2, causing the bottom of the openings within such space and on each side of each unperforated portion to be more or less closed up. To avoid this injury to the mold and materially increase its life, I provide a raised bearin plate attachment which I usually make from thin sheet metal of preferably about one-eighth of an inch in thick ness, which plate is provided with 8. marginal rim portion 13 connected by cross sections 14 arranged to underlie the unperforated portions 11 of the mold. The outer edge or rim of the attachment 13 conforms in shape to the outer edge of the mold, the width of this rim being equal to or slightly less than the shoulder 9 and the unperforated peripheral space 12 of the mold. The plate has holes 1.5 to receive rivets, screws'or other suitable means to fasten it to the underside of the mold, its cross members 14 being arranged so that they underlie the unperforated portions 11 of the mold and project the thickness of the late below the bottom surface of the mol so that as the mold is dropped into place the plate strikes the spider and protects the mold from in- J i nother advantage in having the raised bearing surfaces lies in the fact that the mold can be so readily adjusted with its unperforated portions in line with the spider, the o erator being able to reach under the cylinder and readily grasp the cross sections 14 and move them into position above the webs and thus adjust the mold without having to look to seethat all the openings will clear the webs as is now necessary.

In view of the high cost of the metal from which the macaroni molds are made and the difficulty of grinding off the wires at the bottom of the mold o enings, I prefer to stamp the bearing p ate attachments of harder and cheaper metal and attach them to the molds rather than to form the mold as shown in Fig. 6 with raised bearing porsizes of molds that require three parallel cross webs to support same.

IVhile I have defined my invention as peculiarly appropriated to the art of manufacturing macaroni, yet it is obvious that the manner in which I protect my heavy soft mold will be advantageous in other arts where the mold is dropped into place upon cross supports and has apertures which are liable to be indented and closed by strik inglsaid supports.

aving thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. Circular macaroni mold formed of a thick soft metal plate havin sections thereof perforated and separated rom each other and the margin of the late by narrow unperforated sections, and hard metal raised earing surfaces attached to and disposed along the underside of said unperforated sections.

'2. A circular macaroni mold formed of a thick soft metal plate adapted to be supported on a spider and having narrow marginal and transverse unperforated portions adapted to overlie and substantiallyconform to the design of its spider support and having perforated portions between the unperforated portions, and a hard metal attachment for the underside of the mold com rising a plate, substantially shaped to con orm to and fit under said unperforated portions, which is raised relatively to the perforated surfaces of the mold.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
